4.9 Naphthenic Di-Aromatics
Regression method-based BCF predictions for naphthenic di-aromatic hydrocarbons
(Figure 53) are above the B criterion of 2000 for structures ranging from C15 to C23.
When biotransformation is incorporated to the model, none of the BCF predictions are
above 2000 (Figure 54). In support of model predictions, no aqueous or dietary BCF that
is available for naphthenic di-aromatics structures is above 2000. Furthermore, all
experimental BMF values (Figure 55) are below 0.1. It can be concluded that based on
the available data, naphthenic di-aromatic hydrocarbons, as a class, are not
bioaccumulative or very bioaccumulative.
